In Duriano, progression doesn’t just come from survival, it comes from choice. While your first runs introduce a few reliable weapons, many of the most unique tools in the game are locked behind one key resource: Fertilizer.
Earned through gameplay, Fertilizer is a special currency used to unlock new weapons, each offering advanced mechanics and scaling potential. These weapons aren't just stronger, they're built for players who understand the game’s deeper systems and want to explore new build archetypes.
Here’s a look at the current unlockable weapons and why they’re worth every drop of Fertilizer.
Yggdrasill Staff – Arcane Explosion Mastery
Unlock Cost: 250 Fertilizer
Weapon Type: Ranged
Scaling: 100% Spell Damage
Special Effect:
- +2 Weapon Damage per level
- +2 Spell Damage per level
- Attacks explode, dealing Spell AoE damage in a radius
This staff is a caster’s dream. Once unlocked, it becomes one of the best tools for Spell Damage scaling, especially with Trails like Mimir or Frigg. Ideal for AoE control and burst-focused builds, the Yggdrasill Staff turns every projectile into a spell detonation.
Rúnar’s Vex – The Living Thornfield
Unlock Cost: 250 Fertilizer
Weapon Type: Melee (Aura)
Scaling: Thorn
Special Effect:
- +2 Weapon Damage per level
- +2 Thorn per level
- Constant aura damage around the player
Unlike traditional melee weapons, Rúnar’s Vex doesn’t swing; it surrounds you with passive damage. Perfect for builds focused on HP, regeneration, or Thorn stacking, this weapon pairs beautifully with Trails like Eir or Forseti. Once unlocked, it opens up entire new playstyles for players who like to tank damage and deal it back without lifting a finger.
How to Get Fertilizer
Fertilizer is earned by completing runs, clearing chambers. The more you play, the more you’ll gain. It’s designed as a long-term progression resource, letting you unlock gear that matches your growing mastery of the game.
Pro tip: Focused builds, efficient clears, and deeper runs will earn Fertilizer faster.
Why These Weapons Are Locked
These aren’t beginner tools. Unlocking weapons through Fertilizer:
- Encourages you to explore multiple build paths
- Gives a long-term goal beyond each individual run
- Ensures you’ve developed a feel for synergy before wielding advanced tools
Each unlocked weapon dramatically shifts the way you approach combat and progression rewarding knowledge, not just currency.
We want every unlock to feel like a new chapter in your build journey — and Fertilizer is the bridge that gets you there.
Spend wisely. Build boldly. And find the weapon that fits your fate.
